Abstract: Chalcogenide semiconductor nanoparticles and their self-assembly structures have become the most explored group of semiconductor nanomaterials due to the interesting physics involved in quantum confinement, surface chemistry and variety of applications. In the last couple of decades, facile routes for their synthesis and strategies for controlling the size, shape and morphology have been reported. In the present review, synthesis strategies of size and shape controlled nanoparticles belonging to II-VI group of semiconductor chalcogenides are presented and each method for preparation of nanoparticles is critically analysed. Role of various factors that affect the nucleation and growth of nanoparticles is discussed at length. Nanoparticles and self-assemblies of CdSe, CdTe, HgTe and ZnSe are synthesized using new and facile single molecular precursor based noble route by our group that uses non-pyrophoric, low temperature and non-toxic chemicals, their properties and synthesis scheme are discussed as future development in this field. Some recent applications of chalcogenides QDs in the fields of solar cell, optical fibre amplifiers, biosensing and bo-imaging are discussed and reviewed.

Abstract: A solvothermal method has been developed for the synthesis of Cd1-xZnxS (x = 0–1) nanorods from a class of easily obtained, air-stable single-source molecular precursors, cadmium zinc bis(N,N-diethyldithiocarbamates). The phase, morphology, size and optical property of the resultant products were characterized by X-ray diffraction, transmission electron microscopy and UV-vis absorption spectra.

Abstract: The synthesis of hexagonal phase Mn-doped CdS (Cd1-xMnxS) nanorods was achieved by solvothermal treatment of a class of easily obtained, air-stable single-source molecular precursors (cadmium manganese diethyldithiocarbamates, Cd1-xMnx-(DDTC)2) in ethylenediamine at 180 °C for 12 h. The structures and compositions of the as-synthesized products were characterized by X-ray diffraction, energy dispersive X-ray spectroscopy and transmission electron microscopy.

Abstract: The synthesis of phase-pure CuInS2 microclusters comprising nanoflakes was achieved by solvothermal treatment of copper indium diethyldithiocarbamates (compositionally CuIn-(DDTC)5) in ethanol at 190 °C for 36 h. The obtained product was characterized by X-ray diffraction, Raman, energy dispersive X-ray spectroscopy and field emission scanning electron microscopy. Besides, contrast synthesis tests using multi-source precursors were also conducted.
